or. patches for the. inner, tubes. of vehicle.

l tires, the object of the invention being to provide a device of this character which is easily Vand quickly attachable to the-.innen tube and which will effectuallyy prevent. the.

same from protruding through 'a puncture hole. or weakened portion in theouter casing,l of the tire.

Another object of the invention resides in the provision of a guard or patch for the above purpose consisting ofr a body member of non-elastic material provided with lacing eyelets, an inner liningx f or said body of greater length than the same having felt or, other nonfabrasive bindingfmaf terial secured toits end edges to preventifriction upon the inner tube, and a protecting tongue secured to one of the longitudi` nal edges of said inner lining and provided with an overlapping flap to lie beneath the laced edges of the body and against the inner tube, said tongue permitting of the equal expansion of the end portions of the guard or patch and preventing the tube -from being blown back ybetween the patch and the outer casing of the tire. y A still urtherobject ofthe invention is A to vprovide a patch for the inner tubes of pneumatic tires which is simple and durable in construction, may be inexpensively manufactured and will eihciently perform the function for which the same is devised.

lVith the above andv other objects in view, the invention consists of the novel features of construction, combination and `arrangement of parts hereinafter fully described and claimed, and illustrated inthe accom panying drawings, in which- Figure l is a view showing my improved guard or patch applied to the inner tube of" the tire, the tire casing being shown in section; Fig. 2 is a longitudinal section; Fig.'

3 is a section taken on the line 3-3 of Fig. 2; and Fig. 4 is a plan view showing the patch or guard open.

Referring in detail to the drawing 5 designates the outer. casingof a pneumatic tire such. as iscoinmonly used, onmotor vehicle wheels, and; 6 indicates. a. puncture hole in said tirecasing. The innertube 7 is adapted tobearranged within the outer casing of the tire in the usual manner and to that..

portionof thetube underlying. or adjacent to. the opening: 1n the tirecasing, my im? provedipatchor. guard adapted to be applied. v

The` ends. ot this. canvas... bodyare folded unan, the Central.- POatOnz. thereof SQ that the bedr 0fr gaand@ of a three-ply '131% end:.edges ofl the body ofI the ad aent; to the folds. thereof are 01;* 8111111 2b. fabrfftlhefbd ted ai. 'Y .1,1 isV secliredl'-vv This 1mi' l'n y' i l SQYQIMJ layers-10i.: 'plies of the ahnicrbodyt anersecurly stitched together as indicated g as wellas the 'well as the inner lining 11 thereof are preferably cut or woven on 'the bias whereby a maximum of .durability is obtained in the use of the device.

. It be noted vthat the edges of the inner hning ll at the ends of 'the guard ex-4 tend beyond the edges of the body, and theseV extending edges of said inner lining are provided with binding strips of felt or rubber 14, their purpose also being to frictionally engage upon theinner tube and prevent movement of the guard with relation to said tube. To one end of the inner lining 1l a tongue piece 15 is stitched at its central por tion, the'end portions ofsa'id tongue-piece being freeand extending longitudinally upon the inner tube beyond the ends ofthe patch. By securing this tongue only at its central portion to said lining, an equal eX- 'pension of the 'end portions of the guard or patch when the tube is iniatedis permitted,

said tongue also. obviating the liability of the rubber` being blown between the outer surface of the patch and the inner Wall of the tire casing. It will further be noted that one of the longitudinal edge portions of the tongue l5 extends beyond the eyeleted edge oi' the body S.` and forms a iap to ex tend Vbeneath the opposite eyeleted edge of said bodyto prevent the softrubber of the inneil tube being caught or pinched between l the opposed edges ot the patch body when they are brought together and tightly laced.

By means of my improved tube guard or patch, the period ot' usefulness of tire casings is ,greatly prolonged as they may still be employed after being weakened by hard usage, Without liability of injury to the inner tube. The patch or guard may yalso be easily and quickly applied to the tube and doesnot interfere in any manner with the proper inflation thereof.- Owing to the 36 may be folded into sinall compass and'` placed in the pocket or compactly stored.

Owing to 'the simplicity of the construction of my 'improved tubeguard, it will be obvious that the same can be manufactured at small cost and that it is also highly durable and etlicient in practical use.

lVhile l have lshown and described the preferred construction and arrangement of the various parts, it will be understood that the device is susceptible of` considerable` 5 modification without departing from the essential feature or sacrificing any vof the advantages thereof. K v

Having thusdescribed'the invention what is claimed is l A blow-out guard for inner tubes coniprising a multiple-ply ,non-elasticffbody, an

innerlining for said body extending beyond the opposite ends thereof, lsaid lining and the several pliesl of the body being stitched together,l friction inducing bindingr strips secured to the proj ecting ends of said lining,

and a tongue secured at its-centralportion i to one end of the lining and extending be` yond the bound edges of the lining longi-. tudinally upon the tube, l and means. for securing the ends of the body together around the tube.
